Storage Module and Method for Datapath Bypass

A storage module comprising:

• a memory;
• a data path comprising a plurality of components for processing a set of units of data read from the memory, wherein each component is associated with an instruction queue;
• and
• a context interface module configured to perform the following in response to an uncorrectable error occurring in one of the units of data read from the memory:
• set a bypass command in the instruction queues for the components to bypass processing subsequent units of data in the set that are read from the memory;
• re-read the unit of data that had the uncorrectable error and the subsequent units of data in the set, wherein at least the unit of data with the uncorrectable error is re-read with a different read condition;
• and
• set a command in the instruction queues for the components to process the re-read units of data.

A storage module comprising:

• a memory;
• a first set of queues for storing instructions to read code words from the memory;
• a second set of queues for storing instructions to process code words from the memory;
• and
• a controller in communication with the memory and the first and second sets of queues, wherein the controller is configured to perform the following in response to detecting an uncorrectable error in a code word in a set of code words:
• store bypass commands in the second set of queues to bypass processing subsequent code words read from the memory, wherein the subsequent code words are read from the memory in accordance with the instructions stored in the first set of queues;
• store commands in the first set of queues to re-read the code word that had the uncorrectable error and the subsequent code words, wherein at least the code word with the uncorrectable error is re-read with a different read condition;
• and
• store commands in the second set of queues to process the re-read code words.
